Citotoxicity of four types of resins used for removable denture bases: in vitro comparative analysis
Objective: To compare the cytotoxicity of four types of resins used for manufacturing denture bases. Method and Materials: 9 disk-shaped samples of four resin (two heat-polymerized, one auto-polymerized, and one light-polymerized), 9 samples of glass (negative control) and 9 samples of lead (positive control) were made according to the manufacturer instructions. The materials were tested by contact with BALB/C 3T3 fibroblast cells. Each sample was tested after 24, 48 and 72 hours. The cellular vitality was verified through spectrophotometric analysis of the solution where the colour is directly related to the amount of metabolically active and living cells. The results were analyzed through…
Analisi sperimentale comparativa in vitro della citotossicità di quattro tipi di resine per basi protesiche per protesi mobile
Scopo di questo lavoro in vitro è quello di confrontare la citotossicità di 4 tipi di resine per basi protesiche: Paladon 65 powder (termopolimerizzabile) (Heraeus Kulzer, Germany) (resina A); Lucitone 199 powder (termopolimerizzabile) (Dentsply/Trubyte Division, USA) (resina B), Vertex Self curing (autopolimerizzabile) (Vertex Dental, Netherland) (resina C), Eclipse Denture Base Resin (fotopolimerizzabile) (Dentsply/Trubyte Division, USA) (resina D). Sono stati realizzati 9 campioni di ciascuna resina, 3 campioni di piombo (controllo positivo) e 3 campioni di vetro (controllo negativo). Gli eventuali effetti citotossici sono stati ricercati attraverso test per contatto con fibroblasti BALB…
